Abstract

Mutations in DNAJC13, DNAJC6 and DNAJC5 have been implicated in Parkinson's disease (PD). To determine if rare coding variants in these genes play a role in PD risk in the Chinese population, we sequenced all coding exons of the three genes in 99 early-onset PD cases and 99 controls, and genotyped 8 missense variants in another 711 PD cases and 539 controls. Besides two common missense variants that did not show association with PD, the remaining missense variants were extremely rare (<0.5%), found in healthy population controls and did not show enrichment in PD cases. Our results suggest that missense mutations in DNAJC13, DNAJC5 and DNAJC6 do not play a major role in PD in the Chinese population.
